Functional Description ? help Back to Top
Source Description
UniProtTranscription repressor that binds specific DNA sequence such as GT3 box 5'-GGTAAA-3' in the SDD1 promoter. Negative regulator of water use efficiency (WUE) via the promotion of stomatal density and distribution by the transcription repression of SDD1. Regulates the expression of several cell cycle genes and endoreduplication, especially in trichomes where it prevents ploidy-dependent plant cell growth. {ECO:0000269|PubMed:19717615, ECO:0000269|PubMed:21169508}.
